Here's the new versions 1.2 of Export to HTML5 and Export to XML/OBJ plug-ins.
Both plug-ins are now based on the management of the new XML entry that was added to .sh3d files in Sweet Home 3D 5.3. The JavaScript part of the Export to HTML5 plug-in now supports pinch for zoom under Android and Windows, and was optimized to draw 3D lines faster.
